It's easy to edit simple text.
It is initially irritating that a page is saved even when I am just hopping over to another tab to check something out in relation to what I am writing here.
I hadn't yet come across a site that used Persona 
for authentication (not sure how to get an "–" to display) nice to see it actually used, and it worked just fine.
I like it a lot that you can view multiple pages on Federated Wiki at once, to the extent that my screen allows for it, e.g. Welcome Visitors and How to Wiki and Add Links , but haven't yet found an easy way to navigate through those sub-tabs other than by editing the URL directly.
I haven't yet figured out what equivalents of MediaWiki's "view source" exist here.
In the following, I will dump a list of links to other Fed Wiki pages that I still have open in other browser tabs, so as to guide me in further exploring this wiki network.
I'm not sure what the best way is to engage with other Fed Wiki posts, sites or people. Perhaps a role for Web-wide annotation tools?
